A composite image of the little girl was shared by millions on social media, and she was identified later that year.

During closing arguments, a prosecutor conceded Rachelle Bond behaved badly but said there's no evidence she killed her daughter. She had admitted to lying about her daughter's whereabouts after the girl was killed.

She also said in court that she and McCarthy used heroin heavily following her daughter's death and that she lied partly to keep the public benefits that helped fuel their addiction.

Bella Bond was known for months as "Baby Doe" as investigators struggled to identify her.

Rachelle Bond testified that McCarthy punched Bella in the stomach repeatedly until she died. McCarthy's lawyer argued that Rachelle Bond was a "monster" and that the prosecution made a deal with the devil in order to put McCarthy on trial.
